Piston Failure
Used a borescope to look in the cylinder and saw oil pooling up on top of the piston, so I ended up pulling the head and it turned out to be the head gasket. #7 was blown completely through and #5 was a little ob-longed, probably close to failing. I was using Felpro 1008 which is supposed to be a performance gasket, so it wasn't a cheap stock gasket or anything. Would you guys just recommend just replacing the gasket (other head too possibly since it's already most of the way apart) and stay easy on it, get a wideband put on and see whats its doing? Flat-mill the heads? Any different gaskets that might do better?
I'm just glad it was the head gasket and nothing else. I didn't even think about the head gasket blowing out into the lifter valley and there's not too many other ways to burn as much oil as it was doing. Huge relief to me :)
